The "cobweb" in this jarring and creatively-filmed story is the environment that traps a normal young woman into drug addiction and makes her suffer through the prescribed cure as well. Radka (Eva Kulichova) lives at home with her neurotic, distant mother. One day, Radka is drugged by one of her mother's boyfriends and either seduced or raped, depending on one's perspective. Once she becomes addicted to drugs, it eventually leads her to a treatment center that's more like a prison than a hospital or clinic. Psychiatrists listen to Radka's stories about her past life with all the sympathy of Himmler or Goebbels listening to a Jew. Radka, in fact, invents an idyllic romance with a Swede as a part of "divulging" her past to the stony-faced therapists. Some harrowing group therapy sessions follow that would be enough to make anyone seek drugs as a relief.
